The team IMP (Integration, Methods and Production) increases its production abilities in industrial manufacturing strain gauge (SG) sensors for piezo actuators. The strain gauge sensor allows to do closed loop control and to improve the accuracy of the multilayer piezo ceramic deformation.
Thanks to the investment of new devices (oven, and wire stripping and cutting machine), CEDRAT TECHNOLOGIES can provide faster and bigger batches of ceramics with strain gauge sensors. The quantity per batch has been multiplied by 10 and can reach 120 ceramics per batch.
Moreover with his strong experience in strain gauge sensor integration, CEDRAT TECHNOLOGIES can provide high quality and high reliability strain gauge sensor which balance the glue thermal dilatation and cancel the creep linked to the piezo ceramic. This industrial process inherits a space qualified process allowing the SG on piezo to offer a thermal drift for the offset lower than 10ppm/°C and a long-term time-stability better than 25ppm/week.
